#### 1.新建控制台应用程序，引入NLog.dll ####

PM > Install-Package Nlog

#### 2.添加配置文件(*注意此时的startup放置位置，放置其他位置会报错*) ####

<?xml version="1.0" encoding="utf-8" ?>
    <configuration>
      <configSections>
        <section name="nlog" type="NLog.Config.ConfigSectionHandler, NLog"/>
      </configSections>
      <nlog xmlns="http://www.nlog-project.org/schemas/NLog.xsd"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
        <targets>
          <target name="console" xsi:type ="Console" />
          <target name="debugger" xsi:type="Debugger" layout="${date:format=HH\:mm\:ss.fff}: ${message}" />
          <target name="error_file" xsi:type="File"
                          fileName="${basedir}/Logs/Error/${shortdate}/error.txt" maxArchiveFiles="30"
                          layout="${longdate} | ${level:uppercase=false} | ${message} ${onexception:${exception:format=tostring} ${newline} ${stacktrace} ${newline}" />
          <target name="info" xsi:type="File"
                      fileName="${basedir}/Logs/info/${shortdate}/info.txt" maxArchiveFiles="30"
                      layout="${longdate} | ${level:uppercase=false} | ${message} ${onexception:${exception:format=tostring} ${newline} ${stacktrace} ${newline}" />
        </targets>
    
        <rules>
          <logger name="*" writeTo="console" />
          <logger name="*" minlevel="Debug" writeTo="debugger" />
          <logger name="*" minlevel="Error" writeTo="error_file" />
          <logger name="*" level="Info" writeTo="info" />
        </rules>
      </nlog>
      <startup>
        <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />
      </startup>
    </configuration>

#### 3.编写代码调用 ####

using NLog;
    using System;
    using System.Collections.Generic;
    using System.Linq;
    using System.Text;
    using System.Threading.Tasks;
    
    namespace TestNLog
    {
        public static class Program
        {
            private static Logger logger = LogManager.GetCurrentClassLogger();
            static void Main(string[] args)
            {
                logger.Trace("Trace Message");
                logger.Debug("Debug Message");
                logger.Info("Info Message");
                logger.Error("Error Message");
                logger.Fatal("Fatal Message");
                Console.Read();
            }
        }
    }
